I would check out the prices of getting stuff galvanised in Holland. It's very reasonable here in the UK. I've just paid £20 to have my tow bar assembly and rear step done. All split in to separate parts. Are you just talking about the diff covers or the whole axles? In the UK I think galving prices range from 50p to £1 for every kg of metal you take along.

The entire axle casing needs some sort of treatment.

That's what you found when you opened it and cleaned it up?
Interesting

It isn't a totally uncommon thing to do.

Glyptal is the paint I know that gets used for this sort of thing. I've just bought a tin - it was 'king expensive.

I was asking if there is a common paint used on Land Rover parts but it seems as though the good folks here have never even heard of paint on the inside...

It does seem to be an extravagant thing for LR to have done in the first place.

Could have been done by a previous owner. Probably a short sighted farmer who kept paint and oil on the same shelf.

Nah I'm pretty sure this is a rebuilt differential.

Some repairer has painted the inside with something like Glyptal - this is the sign of a pukka job.

Glyptal is to help oil drain in engine block (some say rubbish), almost the exact opposite of what you want in a diff.
Not so much a sign of a pukka job, more a sign of Alzheimers. Or possibly a porous casting.

I don't follow your logic. A differential is a mechanism that is kept alive with splash lubrication - oil on the walls of the axle housing / differential is not where you want it to be. If the oil drips off the walls faster that's a good thing. Porosity / surface roughness can be a problem in these castings which is why a good refurbisher will paint the inside if only to help stop the build up of muck and help oil drain (assuming the part will be serviced at some point in its life).

Funny old world but I keep finding differentials (and axles) with paint inside them

This time a series 2a differential =>

I reckon if I find one without paint in it it'll be worth a fortune!
